introduction: sentinel lymph node biopsy is the standard procedure for lymph node staging in intermediate thickness melanoma. in iran, this procedure has not been addressed sufficiently. in this study, we report our experience in this area. methods: ten consecutive patients with intermediate thickness melanoma where included in our study. 1.5 mci of tc-99m antimony sulfide colloid in two divide...

We report on a 59-year-old female patient with an infected vascular graft investigated with 18F FDG-PET/CT. The first of two studies showed FDG activity in the left deltoid and ipsilateral axillary lymph nodes explained by influenza vaccination the day prior. The second 18F FDG-PET/CT showed multiple FDG-avid lymph nodes on both sides of the diaphragm without tracer accumulation at the vaccinat...

follicular dendritic cells or dendritic reticulum cells are important components of the immune system essential for antigen presentation. malignancies arising from these cells are uncommon and the first case was reported in 1986. the most common sites of follicular dendritic cell sarcomas are lymph nodes, especially cervical, axillary and mediastinal regions, but extranodal sites including head...

detection of lymph nodes (lns) involvement by various pathological processes has great therapeutic and prognostic implications. the purpose of this study was to evaluate the usefulness and accuracy of triplex sonography (gray scale, color mapping and spectral doppler) in differentiating benign from malignant cervical lns. we used triplex sonography to evaluate 120 lns in 50 patients. the gray s...

kawasaki disease is believed to be the commonest vasculitis of medium vessels in asian children. however, the majority of children with kawasaki disease continue to remain undiagnosed perhaps because of the lack of awareness amongst pediatricians. the clinical features of kawasaki disease can be confused with other common conditions such as scarlet fever, stevens johnson syndrome, measles fever...

discussion benign metastasizing pleomorphic adenoma is a rare and controversial but distinct clinical entity. although the definition of the term benign precludes metastatic disease, these tumors do not demonstrate any malignant features yet metastasized to distinct sites. it remains to be determined whether this benign metastasizing pleomorphic adenoma is really low grade salivary malignancy. ...

background : invasive ductal carcinoma is one of the most common type of tumors in females, constituting a single large group of breast cancers. there are various prognostic factors, of which tumor grade, size and axillary lymph node metastasis are among the important ones. fine needle aspiration cytology is a commonly used diagnostic technique in the initial evaluation of breast lumps. in the ...

background : sentinel lymph node biopsy is a technique used to identify the axillary node most likely to contain tumor cells that have metastasized from a primary carcinoma of the breast. this technique provides accurate staging with fewer complications than axillary dissection and may result in decreased costs. we designed the present study to determine the accuracy and success rate of a combi...

background: time of day can affect the outcome of medical procedures and surgical operations. the current study was designed to assess whether time of day can influence the quality of breast cancer surgery or not. methods: patients who underwent breast cancer surgery and axillary lymph node dissection in tehran, iran between march 2012 and march 2013 were enrolled. surgeries were categorized in...

  Schwannomas are benign nerve sheath tumors that originate from any anatomical site. Most of the schwannomas are found in the head, neck or limbs. Schwannoma arising in a lymph node is extremely rare. We have found only four cases in the review of the literature. We experienced a case of intranodal schwannoma in a perigastric lymph node. A 72 year-old female underwent cholecystectomy due to ...
